Climate change programme

Climate change presents significant opportunities and challenges for communities and businesses here and around the world. The Council has established a climate change programme to better respond to local issues and opportunities.  

As part of this programme, Council is currently developing a climate change strategy for the district to provide a framework for local action on climate change.

Council has now set a target for the district of having net zero greenhouse emissions (excluding methane) by 2045 - five years ahead of Government’s proposed Climate Change Response (Zero Carbon) Amendment Act(external link)You can read about that decision on Newsline(external link).

In setting these targets, we listened to the feedback we received as part of our consultation on the emissions targets(external link). We also ran a public survey on climate change and the results are now provided below.

The Council conducted a public survey on climate change in May 2019. This survey was completed by 2724 people and the key findings were:

  • Most people surveyed (77%) thought climate change was an extremely important issue.
  • People under 24 years old were the most likely to think climate change was important (81%). 
  • People over the age of 50 were less likely to see climate change as important, although the level of concern was still high at 70%.
  • Women were more likely than men to see climate change as an important issue (81% for women compared to 71% for men).
  • Most people surveyed (84%) thought climate change would have a big impact on them.
  • Most people (79%) agreed that human actions are causing accelerated climate change.
  • When considering how to set greenhouse gas emission targets for Christchurch, most people (84%) thought our targets should be based on robust science and over half (57%) thought they should be achievable and realistic based on planned actions. 20% of those surveyed thought our targets should align with New Zealand Government targets and 5% thought Christchurch targets should reflect our minimum legal obligations.
  • People thought everyone should be doing more to address climate change. Most people (77%) felt that New Zealand businesses were not doing enough to address climate change and over half felt that Central Government (68%) and Christchurch City Council (61%) were not doing enough.
  • Nearly one-third of those surveyed (30%) thought their own household was not doing enough to address climate change.
  • More than half of the people surveyed (65%) felt that their personal actions made a difference to reduce climate change.
  • Actions most commonly taken by people to address climate change were:
    • reducing waste and recycling (93%)
    • saving energy at home (87%)
    • eating less meat (75%)
    • reducing car use (72%)
    • choosing locally made or eco-friendly products (70%)
    • conserving water at home (68%)
  • 11% of people reported to be generating renewable energy at home and 16% said they use an electric or hybrid car or taxi in Christchurch.

Christchurch City Council has a history of taking climate action.

These actions provide valuable opportunities to share, learn and collaborate with other organisations and communities.

They also demonstrate the importance and power of collective action.


In 2008 the Council established and began to implement the Sustainable Energy Strategy 2008 which will be revised in 2019.


In 2010 the Council established and began to implement the Climate Smart Strategy 2010 which will be revised in 2019.


In 2011 the Council crafted and was a founding signatory of the Local Government New Zealand Climate Change Declaration(external link) that has now been signed by 54 Mayors and Regional Council Chairs throughout New Zealand.

This outlines key principles and actions needed for addressing climate change.


In 2015 the Council established and began to implement the Christchurch Energy Action Plan 2015 which will be revised in 2019.


In 2016 New Zealand joined 196 other nations when it signed the Paris Accord. This aims to limit planetary warming to no more than 2 degrees to avoid the worst impacts of climate change for ourselves and future generations.

To achieve this goal, all communities and businesses need to rapidly transition to a low carbon economy reducing global emissions by more than 80% by 2050. This represents a significant challenge and opportunity for innovation, the green economy and for Christchurch.

Taking climate action will result in widespread benefits for our communities.

For example, it will bring about new jobs and business opportunities required to support a sustainable and future-proofed economy under new climatic conditions. An economy that supports strong connected communities where there are good levels of health and wellbeing, a reduction in waste and pollution, and a focus in improving our natural environment. 

In short, it will help make Christchurch an even better place to live for generations to come.


Christchurch joined 7,400 other cities in 2017 when it signed the Global Covenant of Mayors for Climate and Energy(external link) which assists cities to manage emissions and to prepare for a changing climate.

Christchurch was also one of the first Rockefeller 100 Resilience Cities(external link) helping to prepare for our key resilience challenges. 

Also, in 2017 the Council set itself the target to be net carbon neutral by 2030(external link).


In February 2018, Christchurch City Council partnered with Yoogo (now Zilch) to launch a 100% battery electric car sharing scheme for businesses and the public helping to change the way we travel and reducing carbon emissions.

The Intergovernmental Panel on Climate Change (IPCC)(external link) was hosted in Christchurch in March 2018 with a range public engagement events to learn about climate change from specialists from around the world.

Also, by the end of 2018 Christchurch City Council had adopted a new procurement policy encouraging suppliers to minimise waste, energy and greenhouse gases.

Christchurch District's greenhouse gas emissions

Christchurch City Council commissioned AECOM New Zealand Limited to deliver a report on Christchurch Greenhouse Gas Emission Inventories for Financial Years 2018/19 and 2016/17.

The report gives a detailed overview of the Christchurch District’s greenhouse gas emission profile. This is useful to determine which are the key sectors and sources of greenhouse gas (GHG) emissions. This will assist with the development of GHG emission reduction action plans for Christchurch. This GHG emission inventory reporting also assists Council to meet the Global Covenant of Mayors for Climate and Energy reporting requirements that Council is a signatory to.

Some key findings from the report include:

  • In the financial year (FY)2018/19 on-road petrol and diesel use was the highest emitting source within the Transportation sector’s GHG emissions and produced 36% of Christchurch’s total gross GHG emissions.
  • On-road petrol and diesel use increased by 2.3% between FY2016/17 and FY2018/19.
  • In the FY2018/19 electricity consumed produced 10.4% of Christchurch’s total gross GHG emissions.
  • Total gross GHG emissions increased by 2.2% from 2,665,643 tonnes of carbon dioxide equivalent (tCO2-e) in FY2016/17 to 2,723,016 tCO2-e in FY2018/19.
    Christchurch’s per capita GHG emissions for FY2016/17 and FY2018/19 have remained steady (7.1 tCO2-e per person) and were below per capita estimates for New Plymouth (FY2017/18) and Dunedin City (FY2018/19), the same as Auckland (FY2015/16) and above the per capita estimate for Wellington City (FY2018/19).

Christchurch City Council's greenhouse gas emissions

Council has set a target to be net carbon neutral (net zero greenhouse gas emissions) by 2030 for Council’s activities.

During the 2018/19 financial year reporting period Council emitted a total gross 21,862 tonnes of carbon dioxide equivalent (CO2-e).

Council has implemented an internal Resource Efficiency and Greenhouse Gas Emission (REGGE) programme of work. This includes implementing an internal REGGE policy, [PDF, 297 KB] a management structure to deliver on this policy, internal REGGE management plans (energy, GHG emission, solid waste and water management plans), and an internal REGGE dashboard to monitor energy use, GHG emissions, solid waste generation and water use.

Climate change will affect our district in different ways.

Across Christchurch and Banks Peninsula, our summers will become hotter, dryer and longer, and our winters shorter and milder. We are likely to experience more extreme rain, wind, fire and flooding. Some areas will become more prone to drought while our low-lying coastal areas will be more exposed to tidal flooding.

Climate change will affect our way of life. As a city, we need to reduce our carbon emissions and do what we can to mitigate the effects of climate change. We also need to prepare for the changes that are ahead of us and respond to the social, environmental and economic effects of our changing climate.

The Council is working with the community to better understand these changes and to establish ways to proactively respond to these risks.
